The bar 1 is humped in the censprings interposed between the wheels'anrl the frat portion of the middle so that the contact to body of the car. Heretofore, whenever it was ins surface of the cups 2 is substantially in the t5 necessary to lift the front end of a car for mesame level as the center portion of the bar which chanical inspection, greasing, repair, or the lilre, results in better general balance and strength the ordinary lifting jaelr was positioned beneath of the entire assembly and eflects low clearance the front axle at the point clesirecliancl the car of the spring contacting members so essential in raisecl through such contact. With the advent in positioning the supplemental on when on a W of the above mentioned new development in au= jaclr; uncler an automobile of the present low contomobile construction a new problem arose instruction.
